Press and hold CTRL, SHIFT and ESC simultaneously ( CTRL + SHIFT + ESC).

Here are the steps to find and close the Java-based program.

The easiest way to see if the program is running or not is to check the task manager.

The problem can also be caused if you don’t have proper or enough permissions. This is, of course, for the people who are installing Java and not updating. The first one is that the application you are trying to install is already installed. There are a couple of things that can be the root of this problem.

So, closing the application will solve the issue. The Java update won’t install if a Java-based program is running. The error is caused by, as the error message tells you, a Java-based application running in the background. The error will come up with a message saying that you need to close the applications that are using Java and it will give you the name of these applications in a list. This error code is shown when a fatal error occurs during the installation.

However, sometimes you might see an Error Code: 1603 while installing these Java updates. Most of these programs automatically check for Java updates and download them on your behalf or ask for your permission depending on your settings. We should keep the Java technology up-to-date in order for our applications to run at their maximum performance. There are plenty of Java-based applications that are installed on our systems.
